Answer:
(a) (f+g)(x) = √(2x) +x²
(b) (f-g)(x) = √(2x) -x²
(c) (f·g)(x) = x²√(2x)
(d) (f/g)(x) = (√(2x))/x²
Step-by-step explanation:
These are all about the meaning of the notation (f <operator> g)(x). When the operator is an arithmetic operation (addition, subtraction, multiplication, division), the notation means the same thing as ...
f(x) <operator> g(x)
__
(a) (f+g)(x) = f(x) + g(x)
(f+g)(x) = √(2x) +x²
__
(b) (f-g)(x) = f(x) -g(x)
(f-g)(x) = √(2x) -x²
__
(c) (f·g)(x) = f(x)·g(x)
(f·g)(x) = x²√(2x)
__
(d) (f/g)(x) = f(x)/g(x)
(f/g)(x) = (√(2x))/x²
Let's set up the problem. First, we know Texas is 270,000 square miles, and this is 41% the size of Alaska.
So 270,000=41%(size of Alaska), or 270,000=.41(x). Now solve for x to find the size of Alaska.
In order to figure out the horizontal distance Raymond travels using his zip cable, we may simply apply Pythagoras theorem which is, for a right triangle:
hypotenuse² = base² + height²
base = √(hypotenuse² - height²)
base = √(65² - 52²)
base = 39 yards
Raymond will travel a horizontal distance of 39 yards.
